For example, if the url is [@http://example.com/script/tux@], add a fake query string on the end with the desired extension (e.g., [@http://example.com/script/tux?format=.png@]). If query strings are unsuitable, a fragment identifier should work, e.g. [@http://example.com/script/tux#file.png@].%0a%0a* Relative width is possible by using percentages.%0a(:markup:)%0a%25width=10pct%25 http://pmichaud.com/img/misc/bubble.jpg \%0a%25height=30pct%25 http://pmichaud.com/img/misc/bubble.jpg %0a(:markupend:)%0a%0a* '''Flowing text is possible, like captions, within a frame'''%0a(:markup:)%0a>>lframe width=130px%3c%3c%0a%25thumb width=130%25 [[http://pmichaud.com/img/misc/bubble.jpg | http://pmichaud.com/img/misc/bubble.jpg"Burst the bubble"]] | [--Long caption for an image like [[http://pmichaud.com/img/misc/bubble.jpg | the bubble]].

For images that are attachments, the general format is [@Attach:Groupname./image.gif@].  To link to an image that is on the same server, use [@Path:/path/to/image.gif@].%0a%0aQ: Can I attach a client image file on PmWiki?%0aA: Yes, see [[PmWiki/Uploads]] .%0a%0aQ: How can I include a page from another group that contains an attached image?%0aA: Include the page in the normal way, ie [@(:include GroupName.Pagename:)@]. In the page to be included (that contains the image) change [@Attach:filename.ext@] to [@Attach:{$Group}./filename.ext@]. %0a%0aQ: Why, if I put an image with rframe or rfloat and immediatly after that I open a new page section with ! the section title row is below the image instead of on the left side?%0aA: Because the CSS for '''headings''' such as ! contains an element '''clear:both''' which forces this behaviour. Redefine the CSS locally if you want to stop this happening, but I think the bottom border (that underlines the heading) would need further re-definition. I just use bolding for the title, and 4 dashes below [=-=]--- to separate a new section, and it saves the effort of fiddling with the core definitions.%0a%0aUnlike the '''lframe''' and '''rframe''' directives, '''cframe''' does not fully honour the width setting. While the frame itself resizes to match the request, the enclosed image does not, and retains its original width. Effect is the same in IE and Fx. I've added an example beneath the standard example above.%0a%0aQ: Is it possible to disallow all images?  I already disabled uploads but I also want to disallow external images from being shown on my wiki pages.%0a%0aA: Yes, add to config.php:%0a->[@%0aDisableMarkup('img');%0a$ImgExtPattern = "$^";%0a@]%0a%0aQ: How can I make it so that when I place an image in a page, the block of text it is in is a %3cp> (paragraph) rather than a %3cdiv> (division)?%0a%0aA: If you just want it to happen for a single image (instead of all), then%0atry putting [@[==]@] at the beginning of the line, as in:%0a%0a->[@[==] http://www.pmwiki.org/pub/pmwiki/pmwiki-32.gif@]%0a%0aHaving [@[==]@] at the beginning of a line forces whatever follows to%0abe part of a paragraph.%0a%0aQ: Is there any way to use relative paths for images?%0aA: See Cookbook:RelativeLinks and $EnableLinkPageRelative.%0a%0aQ: Is there a way to attach a BMP and have it display rather than link?%0aA: Add to config.php the following line:\\%0a @@$ImgExtPattern = "\\.(?:gif|jpg|jpeg|png|bmp|GIF|JPG|JPEG|PNG|BMP)";@@\\%0aNote that BMP images are uncompressed and quite heavy. You may wish to convert them to PNG (lossless) or JPG (lossy) format, and thus reduce 5-20 times their filesizes.%0a%0aQ: Is there a way to have a table to the left or right of an image?%0aA: Yes, see [[(http://www.pmwiki.org/wiki/Test/)TableAndImage]].
