Ummm....just wondering...how the HELL can tou post a decent thumbnail at less than 15K? Somebody PLEASE let me know - I cannot posy images without a thumbnail, and I can't get them below 15K. HELP PS - I'm Mac based

Ya, right at the moment I'm confused. Am I doing something wrong? Many of the 100X100 thumbs on the front page are down around 3K. The 200X180 thumbs in Poser and Bryce are below 15K. A 100X100 saves at about a 36K uncompressed tiff, which is about what I'd expect. I'd think a "Low" quality jpeg would give a 40% compression easily. I guess I'm not too bummed if 'osity reduced the thumb size; it should make browsing faster. [I wonder if a 112X112 thumb would actually compress smaller than a 100X100???]

Sorry Wolfsnap, I'm not sure about Mac...do you have photoshop? The "save for web" function always gets my thumbnail sizes down (admittedly at a loss to quality)...but it's the main image that counts surely? The thumbnails are just a "teaser" Look at my gallery thumbs...all are below 15kb...most give a general idea of what the picture is like (probably why I don't get manyy people looking at them lol)
You can post an image into the galleries without a thumbnail if you want. The thumbnail is optional.

As PunkClown has said in an earlier thread it's always been 15K. If you take a look at my thumbs, you can see they really don't looks so bad...I average around 10K consistently. 200X200 with a compression ratio of about 40 on PS.....

I am, therefore I create.......

I don't know if you have this option turned on in Photoshop....so it makes the preview icon and preview thumb etc.

When it is turned on, it basicly saves 3 copies(in different sizes) of your image...making your file size bigger than it needs to be.

If you turn it off (in photoshop prefrences) it will reduce your saved file size. This might be what is happening to you?

No more nice little preview icons, but a good naming scheme will take care of that.

-my 2 cents

"save for the web" on photoshop 7 is a good solution.


Misha883 ( ) posted Thu, 27 February 2003 at 8:01 AM

That "Save for Web" is a GREAT option! [Now, I'm going to have to try it on not just the thumbnails...]


vod ( ) posted Thu, 27 February 2003 at 8:20 AM

Me too !!!

You can also use InfranView to scale tehm down. I use it and it works great.

*Mac users seems to have problems to upload their thumbs. Here is what a user wrote: this will be tricky for us Mac users - when i download a thumbnail from today for example, my Mac tells me that it has 164 Kb!! On my Windows machine it has 14 Kb. The difficulty is, that a Mac tells me not the exact (windows file) sizes but the needed size (blocks) on the hard disk. So how can we poor Mac users find out how big something really is on a Windows machine. Maybe the admins should tell us a Mac file size too. This would be great!* and *... and Adobe's JPEG "web export option" on MAC always indicate the exact file size in KB.* Hope this helps all those Mac people and you Wolfie!

I am, therefore I create.......
