WebImage: Working with Comments

<--Back to WebImage Tech Support

Q: Why do the comments keep disappearing after I've saved my image?
A: Although comments are available for other image types, WebImage v2.1 only supports comments in GIF and PNG images.

Q: How can I add another comment to my first comment?
A: GIFs support multiple comment pages. To add another comment page, simply press the right arrow under the comment box until the caption says "new comment". Then, when you enter text, the caption will update to display the current page and the total number of pages.

Q: How can I insert a new comment in between two old comments?
A: There is no way to insert a comment between two others. You can however add your comment to the end, then select and cut the text from a comment which will delete it then paste it at the end of that one.

Q: How can I delete some of these comments out of my GIF file?
A: To delete a comment, simply delete all the text in the comment. The comment page numbers will adjust themselves.

Q: Why can I not save comments in JPG and TIFF files?
A: WebImage does not currently support comments in any file type except GIF and PNG. In the future, we plan to support comments in every file type we support which allows them.

Q: Why does WebImage keep adding the word Comment: to my comments?
Q: How exactly does WebImage handle PNG comments?
A: PNG comments are different from GIF comments in that PNG comments have two fields, a keyword field and a comment field. The problem is that both fields are mandatory for a PNG comment and so, if no keyword is present, WebImage adds the word Comment into the keyword field. WebImage uses a colon to separate the keyword from the actual comment. For comments with keywords, everything before the colon is considered a keyword and everything after is considered the comment proper. For file types like GIF, which do not require keywords, everything before and after the colon is saved as a comment. Although it seems clunky at first, this manipulation was necessary to allow smooth conversion between images of different types.
