Let''s say the file is a TIFF image - can the helper create a JPG version of the thumbnail for display in the browser? Curious if the plug-in can handle that transform with some creative use of the

Hi, I have a some image files that belongs to some users. Only the owner of an image should be able to see it. How can I do that? I don''t think I can use send_data, because I want the image to be displayed on a "rendered" page.

First time on the browser everything looks fine, upon clicking the link, it contacts the server and displays in IE brwoser the image that was stored on the server. But in case if the image gets changed on the server(File Name being the same), then even though i

Hello list, despite I already posted a mail on this topic on R help, I guess this place may be more appropriate. I'll make it shorter this time. Sorry for posting twice. I found that using pixmap pictures in a Sweave document was sometimes almost impossible, due to the huge size of the pdf pictures produced. The first solution I found was to save pictures in png, when too heavy in pdf.

Dear experts, I have rail site that is running lighttpd and fcgi.

One of my problems is I can''t find the httpd.conf file for
