HOWEVER, i assure you i am using your library :P Anyway i was curious is there a setting to enable caching in your library so that the images don't refresh every time i go to the site? If not do you have plans on implementing such a feature in the future?

Upload file size is, however, ultimately restricted at the php.ini level, but you can do so programmatically. Since the library doesn't have any official file upload support, that's about all I can do to help you, but there are tons of articles on file uploads in PHP out there. jay on "Were do you set the maximum size for the image upload??" http://phpthumb.gxdlabs.com/forums/topic/were-do-you-set-the-maximum-size-for-the-image-upload#post-140 Sat, 28 Nov 2009 19:30:40 +0000 jay 140@http://phpthumb.gxdlabs.com/forums/ Were do you set the maximum size for the image upload??

On some slower servers the caching is a really nice feature to have. Am I not using the software correctly, or is it actually missing from version 3? If it's missing, are there any plans to introduce it? Whilst leaving this message, I'd like to say what a great bit of software I think php Thumb is.

Basically what's happening is that you've started output elsewhere in your PHP code, and when the library tries to send headers for the image itself the exception is thrown. This is because PHP has already sent headers to the client, and once that's done you can't send anymore (headers were sent as a result of prior output started). Basically, removing this code from my library won't do anything for you... you'll just see essentially the same error thrown, but this time from PHP itself, rather than an exception thrown by the library. Hope that helps :) phillw on "XHTML Strict & phpthumbs" http://phpthumb.gxdlabs.com/forums/topic/xhtml-strict-038-phpthumbs#post-106 Mon, 21 Sep 2009 13:19:59 +0000 phillw 106@http://phpthumb.gxdlabs.com/forums/ Oops ...

I'm sorta guessing that most browsers can handle jpgs & gifs - w3c has this to say on the matter.... <blockquote>Attributes of this type identify the allowable content type(s) of an associated URI (usually a value of another attribute on the same element). At its most general, it is a comma-separated list of media ranges with optional accept parameters, as defined in section 14.1 of [RFC2616] as the field value of the accept request header. In its simplest case, this is just a media type, such as "image/png" or "application/xml", but it may also contain asterisks, such as "image/*" or "*/*", or lists of acceptable media types, such as "image/png, image/gif, image/jpeg". The user agent must combine this list with its own list of acceptable media types by taking the intersection, and then use the resulting list as the field value of the accept request header when requesting the resource using HTTP. For instance, if the attribute specifies the value "image/png, image/gif, image/jpeg", but the user agent does not accept images of type "image/gif" then the resultant accept header would contain "image/png, image/jpeg". A user agent must imitate similar behavior when using other methods than HTTP. For instance, when accessing files in a local filestore, might cause the user agent first to look for a file logo.png, and then for logo.jpg. If a value for the content type is not given, "*/*" must be used for its value. For the current list of registered content types, please consult [MIMETYPES].</blockquote> So, placing a <code>In its simplest case, this is just a media type, such as "image/png" or "application/xml", but it may also contain asterisks, such as "image/*" or "*/*", or lists of acceptable media types, such as "image/png, image/gif, image/jpeg". </code> type statement would keep me in alignment with the rules - My question then is, what would be, if any, the effect of removing the code from your library with those directives in ? -- Yeah, I know I'm a pain in the ass, but, please try to see it my way - I already have a header section to look after all my pages, and I would be most pleased to be able to adapt to use your fantastic php-code.
