I use Paintshop Pro for post-processing and have done for sometime with two different cameras. I upload pics to ABPics, which requires file size of no more than 500kb. Paintshop Pro enables me to reduce file size very quickly and easily...... until the last few days when I have had several pics rejected by AB. The problem is pixelation, i.e. you can see pixels on the compressed pics. Also, sky scenes are not smooth, but have clumps of varying colours where the clouds should be. Here's a typical example:
Any ideas, please?
