SOS: Please could someone help a first time user? There are .jpg photos of drawings I took pictures of, and need to put a white background on a black-ink flower design. Then I have Water-element Tai-Chi motif and between its wavy lines I want to place a title of a text that can bend according to these lines.
To be honest one problem is MacOS and that not making use of Gimp very transparent. Gimp can be used very successfully as-is and extended by use of scripts and plugins. You need to know where those 'extras' go. Next some of the more useful ones might not be available / work with MacOS.
For changing the background, this is a subject which comes up frequently and there are as many methods as questions. It all depends on the image, is it a plain background or patterned ? Does the original paper have a texture ? Always best if you can post a typical clip of the photo.
This is a (clip) photo of a line drawing, with a reasonably uniform background and I got a result like this 40 second animation,

1. The Colors -> Levels tool see:
https://docs.gimp.org/2.10/en/gimp-tool-levels.html
2. Increased the density of the lines Filters -> Generic -> Erode
3. Cleaned up the background by colour select. Note the increase in the threshold to get a better selection.
4. A bucket fill to fill the selection with white. (I drag-n-drop the white swatch into the selection)
Text on a curve all depends on the curve, with standard Gimp it might go like this

1. Make / Adjust a path
2. Make a line of text and with standard Gimp you will probably have to pad-out the text
3. Create a new path of text characters Layer -> Text Along Path
4. Fill the text-path as required.
If the text-path is distorted then you might need a third party plugin such as Ofnuts text-along-path plugin. see:

Thank you for excellent instructions

Do not thank until you get a result ?
If you give more details then you should get better suggestions, especially on background removal.
Thank you Rich2005 THE PICTURES SEEM TO BE ENCLOSED AND I DID SOME WORK ON THEM ALREADY TO MAKE THINGS SIMPLER. THE FIRST IS A YAK-TYPE ANIMAL THAT USUALLY HAS VISIBLE HORNS. IT NEEDS DIFF. SHADES OF GREY CHOSEN FROM THE EXISTING BACKGROUND AND THEN FILLED. THE "BUCKET FILL" I COULD NOT FIND YET.
THE SECOND IS WHAT I CALL A WATER ELEMENT PHILOSOPHY" EMBLAM, AND BOTH ARE DONE BY A TIBETAN ARTIST, SO I ASKED HIM IF HE DID NOT MIND IF YOUR TEAM WOULD LIKE TO KEEP THE DRAWING AS USEFUL SKILLED ARTWORK, AND HE SAID THAT IS OK.
I WANTED TO PLACE JUST A STRAIT-LINE TITLE IN BETWEEN SOME LINES OF THIS SECOND PICTURE, AND THEN ALSO IMPORTANTLY FOR A BOOK COVER, I WANTED TO STRETCH IT SO IT PRINTS AT 7" X 9". I HAVE JUST DOWNLOADED LIBRE-OFFICE TO FORMAT THE PEACE-BUILDING BOOK I WORK ON, SO I GUESS THIS GIMP WILL BE MY MAINSTAY.
