Suddenly my slides disappeared. I don't know when it happened. Maybe after some updating?
I don't find solution.
Drupal 7,39, theme Marinelli.
I tried to delete this theme and install again, but no result.
What can be? Could somebody help me? My site

<img class="slide" id="slide-number-0" longdesc="" typeof="foaf:Image" src="http://www.sniegonuoma.lt/sites/default/files/banner/zydi_kalnai_1020_320.jpg" alt="" title="">

First, make certain that /sites/default/files/zydi_kalnai_1020_320.jpg exists. If your originals have gone missing, nothing else is going to work.

Then make certain that the "banner" image preset is configured.

Then make certain that Drupal has the rights to write files in /sites/default/files/ and /sites/default/files/banner/ directories.

1. Yes, all images are in the place.

3. /sites/default/files/ and /sites/default/files/banner/
has 755
2. explain please what means "banner" image preset is configured"? Where and what to look?

It is strange for me, that slides worked for many years and suddenly they stopped. It seems something prevent, maybe some conflict
I have something installed last time but don't remember what

Drupal 7 calls them "image styles." See /admin/config/media/image-styles, where you should see a "banner" style defined. This tells Drupal how to create the derivative image that is specified in your design.

Look in your filesystem to see whether the derivative image exists. If so, it should be served by Apache without Drupal being involved. If not, Drupal should create one one the fly (which is why Drupal requires write-access to the directory). It's possible that the file exists but is corrupted. If it does not exist, and Drupal is unable to create the derivative, you should be getting errors in your Drupal "watchdog" log.

You also should examine the webserver error logs for other evidence, such as PHP errors, out-of-memory conditions, etc.

Thank you, that you are and try to help me, but I am sorry not experienced with Drupal. I have created only two websites with Drupal (but I am very good with Joomla)

There wasn't Banner style in my images styles. I have added "banner" but couldn't change properly size 1020x320 (?)
The question: why previously slides worked and what could happen?
What is derivative image and where to look it? What is format?

Please explain in details

I have no idea what might have deleted the "banner" style from your configuration. Your HTML example clearly expects it to be there.

What is derivative image and where to look it? What is format?

A derivative image is just that -- an image derived from the original. It is created from the original when first requested by a browser, and cached so that all subsequent views are delivered directly by the webserver.

An image style can apply any number of transformations, including resizing. Here is a video tutorial:

1. I changed the size of banner style, but I don't see some image in my image style manager. When I click to view I get forbidden:
although the images are in sites/default/files/banner/

2. After that I have moved .htaccess file from this directory to my hard disk and first image appeared but no slides

3. How and what change in .htaccess file I don't know while I am not programmer :-(
4. How to compel slides to work I don't know. At least finally there is one image but no empty header ... It is better than nothing...
