We've had a request to add alt attributes to the graphics in our .pdf
files so users can search on the graphics; basically, the requestor wants
to replicate the alt attributes on graphics in HTML.. I've googled and
looked at the PDF spec and the closes thing I've been able to find to what
is being requested is tagging the .pdf file. I tried adding tags with alt
text to a couple of graphics in one of our .pdf files, but the reader
search functionality did not find the text I entered. Several of the
resources I've found stated that tagging is used only by screenreaders, so
it probably isn't the solution I'm looking for anyway.

We already caption any graphics that are not inline with text. Are there
other alternatives I may have missed that would make graphics more
searchable in PDF?
