Lorraine...The easiest way is to just copy and paste the link from the shop into your post...you can not hotlink a word in the gallery anymore. The last time Vicki did and update to the gallery it changed....so when you paste a link into the post, once you actually submit the post it looks like [ link ]....and you can click on the word link...I always type out the name of the product then paste the link underneath.
Does this help??
