Est. Budget: $25.00
I have 20 small png images (86x54 pixels) (attached) which represent weather conditions (sunshine, clouds, etc). The surrounding of these objects are currently light bluish and consists of several colors arranged in a grid. I need to make this surrounding transparent, so for example the surrounding of the sun object on a white background is all white.
I'm providing a half-successful example (s2-half-successful-try.png) which has most of the transparency set, but there are still some gray dots present ...
