The pdflatex program allows you to include jpg, png and pdf graphics by default but recent versions (I think this started in TeX Live (MacTeX) 2010 and continues in 2011) will also do a conversion of eps->pdf on the fly (it converts file.eps->file-eps-converted-to.pdf and includes that file). The important thing is to let the graphicx (I recommend the graphicx package, which is built on the graphics package but is easier to use) package figure out that you are using pdflatex by NOT including the [dvips] option in the \usepackage command.

Howdy,

Let me add something to what I said before (it is made clear in that documentation I mentioned in the previous message). The ``restricted shell escape'' default means that pdflatex (using the graphicx package alone and without explicitly invoking the --shell-escape option) can do the conversion file.eps->file-eps-converted-to.pdf and include that pdf file but no other conversions (e.g., tif->png) can be done. If you use the --shell-escape option (TeXShop does use this by default) the graphicx package will include the full epstopdf package so there is no need top explicitly include a \usepackage{epstopdf} command in your document although there is nothing wrong with including that command in case folks with older versions of the graphicx package attmept to typeset the document.

Good Luck,
