Level Select picture problem

[Superusuario]

I have a little problem with my wad in Level Select.
I added my pictures to my levels as 25X25(I think)As shown in the SlumpEd Tutorial.
After that...i save the pictures and open SRB2.I add my file and when i go to check my picture in Level Select...I got a SIGSEGV.(Yes,it is for scr_superusuariosdomain.wad.)Can someone help?

I believe you have to have the resolution to 160 x 100. If you want to use a smaller image, you can surround it with cyan, but I think the image lump needs to be 160 x 100.

Also make sure you named the lump right and convert the lump to DOOM GFX.
