ABRUENIN  It is just the swiss knife of photo editing. Even if you have PS CS4, you will need GC. I do not now a second program which has such rich metadata manipulation functionality. It also has geo tagging functionality ... there are other programs for about the same price which just offer geotagging and nothing else.

AWADO  After ten years of using the (paid) version I still wish it would get a bit more structured in its preferences window. I spent more time searching for a special setting in GC than for an image file on my disk.

POLSEN  Create preview does not work.

NAOH  It appears version 6.5.1 is a minor bugfix for the Universal Binary version.

So far all other variants are on version 6.5.

TANKKNIGHT  Download link takes you to gc website to select a mirror, but nothing happens when you select mirror.  
(Version 6.5)

TALATHARB  Please add this feature NOW:

when in slideshow random mode, pause the slideshow.

now pressing spacebar shows the next random picture, but arrow shows the next picture in alphabetical order.

BUT "next picture" only takes in account the filename.

It MUST use the full pathname instead.

Try to browse your Travels folder by random. At picture Travels/Italy/Toscany/pic023.jgp you pause and want to see all the other Toscany pictures.

But otherwise not dumb GC shows pic023.jpg from Travels/Egypt/pic023.jpg.

This is plain wrong, isnt it?

please mr. lemke, fix this

BLABLABLA@DODGIT.COM  I don't *love* GC, but I like it enough to use it as my main photo management application. (instead of iPhoto.) I paid the $34.95, which is an absolute bargain. I have contacted the developer twice with feature requests. Both times, he responded immediately. One feature turned out to already be in the application, and the other he added and sent me a link to download a beta version with the added feature only days later!! Wow.

This app does a lot, but many of its commands are only to be found by right-clicking. It has been around for a long time, and its features have been added, and added, and added on top of a basic structure that seems inadequate to present them all in a simple and productive way. That's fine with me. It's a little like Eudora used to be... not great (and sometimes downright ugly) in the UI department, but it'll do damn near everything you can think of, so as long as you're patient and not afraid to take a little time and learn how to make it do what you want it to do.

And I love the fact that it'll actually open a TRS-80 graphics file. That's totally awesome!

KAIDOH  Other Reviewers have mentioned it: GC is getting bigger and bigger. But on the other hand this gem is getting better with every release - and updates are coming pretty constantly. Being around for a real long time this app might be a little behind according to GUI polishing but it is still a formidable workhorse I keep coming back to in spite of the new kids on the block (Acorn, Pixelmator and alike - which are fine applications of their own). Everybody interested in serious image processing should give it a try. The functionality you get for the money is hard to beat.

FIREMIN  Thorsten Lemke has been slowly tweaking and adding features to this fantastic app for years. Online support has been fantastic. Several versions ago, I did something unusual with a very large file that caused a crash and he worked very quickly to fix the cause. He offers a genuine shareware product not a half crippled version. It is THE program for opening a wide range of image formats. Despite regular updates, only 1 major revision has required an upgrade fee in the years that I've been using GCon. Thumbs up from Down Under!

KILLER KLOWN KAR  Jeez, once again what a bunch of whiny little bitches. Too many features, too many interface issues. Boo hoo hoo. The interface conforms to Apples guidelines. If that is an issue, Apple needs to revise their interface guidelines. I have used GraphicConverter for ages and still do. It's multi mode batch processing is unequaled for quickness and simplicity. I can quickly crop, size, unsharp mask, convert etc. The concept that it is a 'poor mans Photoshop' is a little off. I suppose a Miro is a poor mans Ferrari. Both have different uses and priorities. Both are good.
