I have finally found time to replace those ugly file names (e.g. 1C4D4616E76602684EA67F3BFB314C209401D40B.jpg
) with much more readable and and SEO-friendly ones. Captions of the corresponding screens are used to generate the names of the screen shot files.
For example, if the caption of the screen is “WordPress 2.5 post editor“, the file name of the corresponding screenshot will be wordpress-post-editor.jpg (or .png, or .gif, the extention depends on the format of the image file).
If you don’t specify the screen caption, or the caption contains non-English characters, the image file will be named pictureN.jpg where N is some number.
