Hi, I think I found a solution to save images from the applet without the need of a server. The solution is supposed to work at least for most current non-'Internet Explorer' browsers.
The idea is quite simple: 1) the javascript Jmol interface requests an image from Jmol 2) Jmol returns the image data to the interface 3) the image is inserted as value into the HTML code of the page for a (predefined?) object 4) the browser displays the image in the page 5) the user saves the image using the "Save image..." dialog I have set up a little demonstration page that illustrates this technique: http://www.fli-leibniz.de/ImgLibPDB/pages/embedded_image_demo.html I had this idea already a while ago but didn't know how to display image data without a file. The tip from the following URL, "http://www.lsc.ufsc.br/~luizd/base64-to-mhtml/workaround.html";, provided the solution. The problem with 'Internet Explorer' is, that the demo page uses a base64 encoded image and (of course) IE seems to be the only current browser that doesn't decode base64 images. But I think for saving images from Jmol it should not be necessary to use base64 encoding. Since the data is integrated as value directly with javascript into the object, I would expect that special characters will not be a problem. I havn't found out yet how to specify the image data without base64 encoding, but it might just be: "data='data:image/gif;...'" instead of "data='data:image/gif;base64,...'" (the '...' represent the image data) I couldn't test if this really works because I had no idea yet how to get the image data into a javascript variable without Jmol providing it. This method should at least work with other browsers, if Jmol would do a base64 encoding of the image. It would be best, if the resolution of the provided image could be set independant from the size of the applet.
