Hello,
I'm a complete noob when it comes to programming and stuff like that, so I need your help...

Here's the problem: I have a picture with 4 irisses (as in example). I want to attach effects like dissolve in sand und crash-effects with lightning. I guess, I nedd some plugins to do this und to vary the parameters for the effects.

Are there some effects / plugins, I can use and / or download for this? I already tried it with the of ChatGPT & Co, but all in all it didn't work.

Thanks in advance for your help!

I am attempting to use the Layer facility. 
I am using the relevant examples in the manual under Chapter 8 of the manual, specifically Figs. 8.2 to 8.4.
The attachment shows my attempt on the lhs to emulate the manual - but I don't get the same results.
Any suggestions?

I can't seem to find a way to use the eraser tool just to erase brush strokes. I can only seem to get the eraser tool to act upon the entire image, erasing to the background, instead of erasing only the paintbrush strokes.

I will better explain with a simple example. Say I have a simple single layer file with a photograph of a person. I use the paintbrush tool to draw a hat on the person. Maybe I don't like what I drew with the paintbrush so I want to erase it, or part of it. I switch to the eraser tool, but instead of only erasing the hat that I drew with the paintbrush it erases the top part of the head also, exposing the blank background. How do I erase just the hat drawn with the paintbrush and not the entire image?

(Hopefully there is a method that works whilst still working on a single layer. I am not experienced enough at the moment to work with layers.)

Any advice would be greatly appreciated.

This is probably a silly question but what is singular in single-window mode?  I used to think it meant literally one window but you can have dockable dialogs as separate windows in both single-window mode and multi-window mode.

Hitherto I have used multi-window mode mainly for two reasons:

1. I put in long layer names to document what I did and often have many layers so having the layers dialog as a separate window allows me to easily adjust it's size.

2. I often like to see more than one image side by side, or a new view of an image along side the original.

This was all fine in gimp 2.10.

In gimp 3 I'm finding window management in multi-window mode OK when one image is open but pretty unusable when more than one is open.

So I'm thinking I could use single-window mode but with dockable dialogs as separate windows, e.g.  the layer dialog on it's own and several others docked together also in a separate window.  Point 1. would still be OK but not point 2.  I'm guessing you can't see more than one image at a time in single-window mode, not even a new view, is that what the single refers to?

For the DOS enthusiasts: DOSBox-X was released on January 2nd, 2026. DOSBox-X is an open source DOS emulator for running DOS applications and games. DOS-based Windows versions such as Windows 3.x and Windows 9x are officially supported. Compared to DOSBox, DOSBox-X is much more flexible and offers more features.

I downloaded the arm64 appimage for 3.0.6 from https://download.gimp.org/gimp/v3.0/linu...4.AppImage, made it executable, and ran it. When I run it, the GIMP window appears, but a) a completely blank "Welcome to GIMP" dialog appears in the middle of the screen. Only the dialog titlebar is visible, and clicking on the "X" at the RH end of the titlebar doesn't close the dialog, and b) if I click on any of the GIMP menus and select any menu option (I've tried about half a dozen different options from different menus), the GIMP windows just disappears.

If I execute the appimage from a terminal prompt, I see the following. I've tried several times, including after a reboot, and the same problem each time.

Hi guys,

I was wondering if you could give me some advice on how I could improve this image I am working on? I am trying to create a space scene with the planet on the verge of exploding.

I am by no means an expert. My trade is structural engineering, so I am very maths orientated, but I am enjoying myself with trying to create something half decent in Gimp. I think the image is okay. I guess perhaps I am trying to reach a level far beyond me.

Thus, some advice and constructive criticism  I would much appreciate.

Many thanks.

When I first opened GIMP v 3.06.1 I started by using MediaDesigns colorization of  a  b/w image  as a guide.

I managed to successfully replicate the tutorial until I had created 4 layers with layer masks.When I came to the 5th layer/mask combination, I could not paint on the image -ie I could 

not see anything happening. I deleted the layer and its mask, andd tried again making sure I had the required palette -which I had constructed - was selected before I created the new 

layer.

This made no difference

As I am unsure as to troubleshooting I am at a loss to know how to proceed.

Also when I began the editing, a long list of palettes was available - this has now disappeared.

Is there an add-on for palettes?

The release of GIMP 3 opens up exciting opportunities to update and extend what plug-ins can do. So he
completely rewrote my GIMP 2 luminosity mask plug-in to take advantage of those new tools.
This new interactive luminosity masks GIMP plug-in lets you choose whether to focus on lights, midtones, or
darks. Then it opens a live preview and a dialog with sliders that allow you to fine-tune your luminosity mask.
That's a much more flexible approach than was available in GIMP 2.

Work with gimp 3.2.0-RC1 don't work yet with gimp 3.2.0-RC2. I've reported it to the author.

When I open a window such as Open, Open as Layers, etc., they keep coming up sorted Z-A. How can I get them to come up A-Z (like normal windows) and stay that way? Even when I select A-Z, then close the window, reopen still comes up Z-A.
