Editing frames on a .gif animation

[Today's Ingredient is]

Hello,
I am looking to edit the timing between frames on an imported .gif animation. I render individual frames in blender then stack them into a .gif using Photoshop.

When I import the 31 frame .gif into PGM it suddenly turns into a 150 frame animation. While importing I see no options in PGM on how to adjust this. I don't understand the reasoning behind this.

In the animation tab there is absolutely 0 options to edit anything.

Links or help would be appreciated

Is it an animated gif? if yes then gimp does the same thing. like if you have 1 animated gif consist of 2 pictures that are animated for 1 second, you open them with gimp and you have 60 frames or something like that instead of just 2. probably put only 1 frame delay between each frames if you don't want something like this to happen.

if your gif is not animated then i dunno ...

Are you adding this gif as a resource in the Animation-only sub tab?

Yes, they are added as Animation-only. Ill try looking into gimp and see if there are options like that in ps. bummer there's no way to edit that in engine.
