Nobody has an answer to this question ??

Have you tried opening a support request with that developer? There's a link for "support" in the Marketplace listing for that add-on.

This is what the developer is saying, when I'm hitting the support button:
Support is available to customers who have purchased this add-on, and team members working on their projects.

So if Somebody had an idea ?

That is not what the developer is saying, it's what the Concrete5 marketplace software is saying :)
(I think you need to click the "add to cart" button on the marketplace page for it to actually recognize you as a customer, not the "download archive" link -- not sure why they have it set up this way for a free addon though).

Anyway, to answer your question: no, there is no way to avoid image compression with this addon. I do have another, similar addon called "Deluxe Image Gallery" (http://www.concrete5.org/marketplace/addons/deluxe-image-gallery... ), which is not free but has several advanced features, including the ability to *not* compress the enlarged images (by leaving the enlarged width and height settings blank).

I'm using the Sortable Fancybox Gallery for my website but ik automatically makes de pictures 96 dpi resolution
Is there anyway to turn this off? or make it 300 dpi?

I also read about the Deluxe Image Gallery
Does that one has this problem too?
And i have made now a lot of pictures en pages with the normal version and concrete 5.
Do i have to make the pages all over again if i switch from one gallery to the new deluxe one?

Already solved

I don't know what you mean about dpi -- computer screens are always 72dpi.
It is true that sortable fancybox gallery images are resized and compressed a little (because JPG's and PNG's are always compressed).

Deluxe Image Gallery does allow you to leave the enlarged images uncompressed (you do this in Deluxe Image Gallery by leaving the "width" and "height" boxes blank or 0), but this only applies to the "zoomed out" images in the lightbox -- not the thumbnail images (thumbnails are always resized).

DPI: dots per inch.
This tells the sharpness of a picture.
If you print something big on paper, 300 DPI is normal.
For small picture on the internet 72 DPI is normally enough.
Your gallery sets our pictures to 96 DPI and compresses them.

Meanwhile, i solved this.

In a file called: "base" in Concrete5 i've set the compression to 100.
This way the pictures are still 96 DPI but the quality better.

Thanks for your reply anyway!

Whoops!

We seem to have overlapped on this post.

Glad you got it sorted.

I don't mean to sound like a besserwisser, but the correct term for screens is ppi (pixels per inch) while dpi (dots per inch) is an old printing term.

Just a side note...

Oh, and by the way, the Deluxe Image Gallery is worth every cent you pay for it!

You need to optimise you photos.

300 dpi?, way to heavy!

Have you watched an 551KB image that's 2m x 1m in size download on a 56k modem?

Optimise your images to an acceptable size and clarity before you upload.

If you use Windows it will default to 96ppi, if it's a Mac it will default to 72ppi (pixels per inch).

You shouldn't need to go bigger than 800 x 600 so it looks good on a laptop.

Experiment with couple of heavy photos until you find a balance between weight and sharpness.

I've managed to get a 1.5MB raw photo down to 235KB and it looked great.

I normally try to hit 150 max, but it's not always possible.

Thank you for this comment -- it explains a lot to me (I didn't know PC's were 96dpi instead of 72, and those sound like good guidelines to use when prepping photos for the web).

Blimey!

It got busy!

I started off with graphics, images and photos.

In the days of 56K modems I was told 'Weight boy, Weight' (not wait).

Back then it was a gif or animated gif, maybe a jpg, NEVER a png!

Going from a Windows98 to a Mac using OSX was a major eye opener!!

Had to learn all over again, a bit like C5.5!

But hey, that's progress...

Not that this is really relevant to most target users, but it's not uncommon for linux users to set their own preferred dpi.
