    Thanks, that’s incredibly useful for something I’m working on, giving Flickr-style size options hadn’t even occurred to me.

    (Quote)WordPress is still lacking in some ways when it comes to handling media.
    Oh, do you mean like when they output style tags right into the body so the page doesn’t validate? ha!

    Great information. I am always trying to find better ways to work with WP’s image attachments. I try not to use gallery plugins and would rather output everything on my own, then incorporate that output into a gallery or presentation system of my choosing.

    For example: Recently, I had to split all the image attachments for a post into before and after pics and this little tip could have made it even more slick. Oh well. Next time.

    BTW – Does this also find any add_image_size custom sizes or just the sizes set in the media settings?

    Justin, this is a perfect example of what I could use for some client sites that I’ve worked on that have been utilizing featured images. We have worried a bit about what image gets pulled with the possible range of sizes a client may upload. Using the information you showed above, I could make sure we likely pull the necessary one and not break the website layout.

    Is there any way to put all formats when we insert an image in the post (in lightbox upload)?

    For example: http://img15.imageshack.us/img15/2844/helpwr.jpg

    Hi justin, thanks for great function.., i just want to ask is there any way to make the image link that we click will be open up in image.php page… what i mean something like this :

    Size : 150×150 , 300×300..etc

    From your function, if i click 150×150.., then it goes to myimage-150×150.jpg..
    I just wondering if you could make it appear in image.php if i click 150×150.. not to image location..

    the link maybe like this :
    Original image.php link

    If click on 150×150 goes to here :

    Can it be done..?

    Is there any working example? I would love to see it, it can be interesting demonstration to show my designers (if I understand correctly what you describe). We launched a new WP site few weeks ago, but handling pictures (since there have been and will be many listings added) has been always challenge.

    Hey Justin, yeah you were right. I’ve been using it. You can add the link not Flickr links only but anywhere you wanted your images to be redirected once clicked. This gave more ideas to those who were not doing this yet.

    This is a sweet piece of code. I’m thinking this could be integrated really nicely with some sort of image gallery plugin on a photography style site. I will give this one a try. Thanks Justin!

    That is a good code for wordpress. One thing I’m trying to do is making lightbox work only on attachment page, anyone tried that?

    Once again, Justin, you deliver the goods!

    I’m developing a site for work, which will be a photo library. Wordpress resizes the images, and users can select a size for print, embedding or using as a thumbnail for our various sites (with various sizes – and yes, custom sizes work).

    Next step is to adapt your code to have have them linked by named size-types rather than their dimensions, and to exclude the thumbnail built-in size (because that’s used only by this site). Suspect the latter will be easier than the former – just need to exclude item [0] from the array…

    Thank you Justin, helpful as usual.
    Next step, I think it would be better to limit appeared sizes into full-large-middle only. The reason is, I don’t think anybody wants to click small 150×150 thumbnail, so I think it would be better if we can limit the sizes. Can you help to do this?

    Is there any way to show the size for all images in the post? or even when using the [gallery] shortcode?
    If this can be done then please let us know, it will help me a lot.

    Is there a way to display category name and tags list at attachment page?

    Although super useful code above, the post actually deals with image dimensions, not the size (as in bytes).

    Would you by any chance know of a good way to echo the file size (in bytes) on the single attachment page?

    Many thanks in advance.
