Transparent image problem

12092005 2021 GMT-5

I have this image that Im laying atop another image. They are both gifs. Im using the eraser tool to erase at 47% the image to make it transparent but, above 50% its 100% and below 50% its 0% transparent.

I am not sure if I've understood exactly what you're trying to do, but it sounds to me like you're working with the image in indexed-mode. Change the mode to RGB (Right Click->Image->Mode->RGB), and you should not have these problems.

Layers->colors->mode->RGB. Then, try again

Gif only allows full transparency or full opacity. If you want to have any other values for transparency than 0% or 100%, you need to use a different file format (e.g. png). Also, as already mentioned by others, make sure the image is in RGB mode.

I suggest you convert both to RGB format, then paste one atop another, then erase at 47% transparency (probably saving as GIMP's internal XCF format if you must stop at any point before you're done). Then flatten and export as GIF.

GIF only supports things being transparent or not transparent, so there is techincally no such thing as 47% transparent in GIF.

You might also want to note the opacity slider in the layers dialogue... maybe that is of some use?
