[closed] Images not working
-
@lukasmaximus It will only allow me to upload BMP or JPG but Bmp have to be super compressed.
Yup followed those steps but just get a black odd shaped box. -
@ajb2k3 I had seen a tweet on twitter.
JPG format needs some conditions.
・progressive off
・not Matte colorand use MS paint is no problem.

Working now.

@ajb2k3 Great!!
-
Is there a good tool in GIMP for compressing image files? @ajb2k3 I tried without success in photoshop before, perhaps its there but I don't know. It would be better however to have an open source solution such as gimp
-
@lukasmaximus some formats gimp can compress, others need understanding of the file formats.
