Window resizing and image thumnail size/position
« on: February 24, 2016, 07:14:56 am »

I am looking for some pointers on how to style image thumbnails in Coppermine such that they will automatically be repositioned and resized to fit the browser window whenever the browser window is resized. I would like to get image thumbnails to be about as responsive to window resizing as, say, the thumbnails located at Wall Haven: http://alpha.wallhaven.cc/random. So, for example, when the browser window is reduced, then instead of the browser displaying a scroll bar and displaying the rest of a cut-off image off-screen, the otherwise cut-off thumnail is carried over to the beggining of the column below.

Any information or pointers would be greatly appreciated  ;)

Take a look at:

Blankstrap - Bootstrap based theme v0.2 http://forum.coppermine-gallery.net/index.php/topic,76309.0.html

Theme Pinmine for cpg1.5.x  http://forum.coppermine-gallery.net/index.php/topic,75270.0.html

 Curve masonry theme ( JavaScript grid layout theme) + bounceIn css http://forum.coppermine-gallery.net/index.php/topic,76859.0.html

Google images grid ( flickr images grid ). Responsive coppermine theme. http://forum.coppermine-gallery.net/index.php/topic,78310.0.html

If you don't like any of the theme.

STEP 1

Paste this code in themes/your_theme_name/theme.php (first make sure function $template_thumbnail_view and function theme_display_thumbnails are not already in your theme.php)

Code: [Select]

STEP 2

Paste this code to themes/your_theme_name/your_file.css

Code: [Select]
.thumbTitle {
    clear:both;
}
.thumb {
    display: inline-block;
}
.tbwrap{
position: relative;
}
.caption {
display: none; .
}
.thumb:hover .caption {
width: 100%;
background-color: rgba(0,0,0,0.5);
color: #ffffff;
position: absolute;
bottom: 2px;
    display: block; .
}
.thumb .image,
.thumb a:link .image {
padding: 0px;
margin: 0px;
}

STEP 3

Go to Config - Thumbnail view and disable Display file caption (in addition to title) below the thumbnail and
Display file name below the thumbnail.

For this layout to work you need to have equal thumbnails (is not really working with diffrent size thumbnails). If you want diffrent size thumbnail then you need Curve masonry theme that also has link to tutorial about how to use masonry in a coppermine theme. Same if you want to display the title or description under the thumbnails and not on hover the thumnail like on the site you posted.

Go to Config - Thumbnails settings - Use dimension (width or height or max aspect for thumbnail)* - choose Exact.
For Config - Thumbnails settings - Max dimension of a thumbnail (width, if you use "exact" in "Use dimension") * and Height of a thumbnail (only applies if you use "exact" in "Use dimension")* use the same number for both.

To update all your gallery thumbnails of already uploaded images:
Go to Files - Admin Tools - click Update thumbs and/or resized photos - click Only thumbnails and Number of processed images per click 10 not 25 or more. Scroll down and click Submit.
