Good suggestions and I understand most of the terms. But what are "alt tags for images" and "alt text" (from your other post)?
I had misspoke (not uncommon). It’s not actually a tag, but an attribute of the IMG tag.
The ALT attribute is meant to be a replacement for an image if the image doesn’t load in the browser. Example: alt="a dulling leaf that is yellowing and curling at the edges." (It’s best when you can think of the alt text as inline text so that it sort of flows with the rest of the text content instead of interfere with it or make for confusion.)
The TITLE attribute is just that, a descriptive title of what occupies that area: title="Photo that illustrates an unhealthy leaf"
Note: ALT text doesn’t "pop up" in amny newer browsers, but TITLE text will.
The LONGDESC attribute would contain an URL to a text page that contains a detailed, long description of the photo like: longdesc="sickleaf_desc.html" (or sickleaf_disc.txt). That page might read like:
——-
Photo that illustrates an unhealthy leaf
This is a photo of a Philodendron leaf that illustrates the dulling of its color and gloss and the yellowing and curling at the edges of the leaf that are the first indicators of a lack of essential nutrients and moisture in the soil.

The IMG TAG would look like this:
<img src="sickphilleaf.jpg" alt="a dulling leaf that is yellowing and curling at the edges" title="Photo that illustrates an unhealthy leaf" longdesc="sickleaf_desc.html" width="120" height="144"
I really need to sort through my bookmarks. The above is as I remember it for somewhere, sometime ago. I’m sure someone will speak up if it’s outdatd info. You don’t do the above with spacer images, an empty alt attribute is sufficient. If I can find my old resource I’ll post it to this thread.
