several picture file formats as .GIF and especially .PNG have text "chunks" in their internal file format to embed comments and other textual information inside the picture file. For example .GIF has a "comment" text field and .PNG has "chunks" for: Image title Author Description (of image) Copyright notice Creation time Software used to create image Disclaimer Warning (nature of content) Source (device used to create image) and a general comment field for conversion from .GIF files Also .PNG has other "chunks" that provide valuable information on data of last image change Furthermore there is information available on the image size, image type (grayscale, truecolour, indexed colour), file size, file creation date etc etc. why not, when right clicking on the image, create a menu entry with "image properties" which calls up a window that gives all the relevant information and a button which when pressed calls up the editor and loads it with all the textual information contained within the image. (note that this can be a _lot_ of text).
Summary: displaying textual data inside .GIG and .PNGfiles → displaying textual data inside .GIF and .PNG files
Having image property might be useful for only advanced users, but not that useful for 90% of the normal users on the net. thoughts?
If might be useful as a tooltip if no title was specified.
Interesting enhancement. Forwarding to Pam, since she's the only person I know that's working on PNG. Pam feel free to reassign if I have hit you with a bug that does not belong to you. I consider it a good request from the "if there is time" category.
a good idea. I'm posting a target milestone way ahead. If I get more time, it may be sooner. -pn

Moving all UE/UI bugs to new component: User Interface: Design Feedback UE/UI component will be deleted.
Component: UE/UI → User Interface: Design Feedback
Moving non-feedback items out of UI: DF in preparation for handover to firstname.lastname@example.org.
Component: User Interface: Design Feedback → ImageLib
This information is a little too much for a tooltip. Displaying the information in "Page Info" could be a better choice.
All pnunn bugs reassigned to Pav, who is taking over the imglib.

I think .JPEG files can store Metadata in them too.
Yes, on JPEGs. I have filed a bug specifically about them as bug 106068.

I think this would be a great feature, along with support for EXIF (bug 232806) and the previously mentioned IPTC (bug 102068). However, I can't seem to find any mention of using internal metadata for alt text in the HTML spec. It certainly sounds like a good idea, though. I'm surprised that there hasn't been any further discussion about this in the last 6 years.
At this point we do not intend to make this work. An extension could be created to support this.
