Large number of photos on a cache page

[+Pezdude]

This is more a technical question, but I'm creating a puzzle that involves 18 different photographs that need to be arranged in chronological order. I'm worried that so many image files on one page might put a heavy burden on some older computers or cellphones. Is there more suitable way of handling this or should I not worry about it?

Perhaps you can reduce the file size of your pictures? Maybe convert them to 72 dpi instead of 300 (or much more).

Hi Pezdude,
do those pictures need to be in very good quality in the cache listing? Otherwise you could use a low quality version of the pictures in the listing and each of those pictures (hyper)link to the high quality version.

I dunno about DPI, but you can experiment with JPG compression ratios.  I've found 82% makes for a pretty compact file with very hard-to-notice image degradation due to the lossy compression.

If you make your images 670 pixels wide, they'll fit exactly into the fixed-frame width the website allows.  Larger and the site will shrink it to 670 for display, with a magnifier icon to make it bigger.  But I'm guessing you don't need it bigger.

18 images @ 670px @ 82% quality would probably weigh in at 2-3MB total, less of course if you use smaller images.  That shouldn't break any decent half-modern browser.

I tend to initially upload my photos to a separate image hosting site. Is it against policy to use smaller versions of the photographs and then include a link to the outside album that contains the full size versions? Or possibly, as  fraggle_[DE] suggested, have them hyperlink to their appropriate full size.

I've never heard of any policy against thumbnail images linked to full-size images.

Here is an example of a cache which have 10 small thumbnail images and all of them are linked to very large images.

In this case all of these images are served from geocaching.com but there is no restrictions to use any service you want.
