Text wrapping around multiple images
Of course, a really neat way to use images in postings is to align them left and wrap the text around them as I am doing here. The thumbnail can be presented without a border as has been done here for this photograph of Discocactus subvridigriseus. The full size image can still be displayed via clicking.
The virtue of text wrapping around images is that detailed descriptions and information relating to them can be included. Plant pictured here is Discocactus crystallophilus
Of course, all this is only really necessary when a considerable amount of text, data, or descriptive information is needed to accompany multiple images. Plant pictured here is Discocactus insignis.
