hello all

I am building a site right now. In my site i am refering pdf file from href text link. Click on the text and the broewser is opening the pdf, Woks perfectly. But want to change the text by an img or thumnail if you prefer. Often in other site i see pdf files reachable via an image and this image often the first page of the pdf file. I mean is there a proper way to code that so the code is telling the browser to get the first page o f a pdf as the linking image. or the only way to do it is to make yourselg a picture from the first page of the pdf file and set it as an href img link?

thnak you all
