That sounds like sensible advice. 900 pix wide is not large so unlikely to be 3 mb file size.
There is an old plugin 'save-for-web' that can both resize and gives a file size estimate in a GUI.
I hope your Win7 is 64 bit, the attached zip includes both 32 and 64 bit versions but the 32 bit webexport32.exe does not work on large images. It does work on smaller images. This an example: https://i.imgur.com/YFNsFHc.jpg
Taking your forum advice about scaling to 900 pix wide yourself. If you do that, do a little pre-blur first. For about 50% scale down, use a gaussian blur with a value of 2. For 25% - use a value 4. Less than 25 % is usually a disaster in my opinion.
You can get an estimate of file size using the regular Gimp export jpeg function. Tick the 'show preview' option. Example https://i.imgur.com/JkWGOYu.jpg
For the save-for-web plugin. Unzip, use either the 32 or 64 bit version depending on your Win7.
Put the file webexport64(32).exe in C:\Users\"yourname"\.gimp-2.8\plug-ins The plugin shows up in the File menu.
The BIMP plugin will resize a collection of images down to 900 wide and apply some sharpening etc. No way to determine the file sizes however.
