I get these two errors when attempting to import my own image.
I do not get these errors when importing the sample images (bitmaps).
I tried opening one of the sample images and pasting my image into it and then saving the result to the same Folder (directory), same errors.
The file sizes are; original 1.6meg, new one = 1.2meg (I used "biohazy.bmp" as my sample file).
"BMP: Couldn't allocate image memory"
"Error in reading image DIB"
Here is a jpg of my file... yes I'm using the bmp version for import.
