How can i automatically resize the images being uploaded to my component? Tried simply replacing 'auto' with '450' in mycomponent_fly.php file. Returns "Not supported" on website. I have 2 images being imported and I need to set 2 different widths.

This is because you must define new sizes in the classes/images.php at the top of the file.
It is a security.

OK I found the file but, i'm not sure which setting to change. The top "define" section or "protected" section? I tried changing this line "SHRENTALS_IMAGES_MAX_WIDTH", 500);

My image was still full size.


@define("SHRENTALS_IMAGES_MAX_WIDTH", 1000);
@define("SHRENTALS_IMAGES_MAX_HEIGHT", 1000);
@define("SHRENTALS_IMAGES_ALOWED_SIZES", '');
@define("SHRENTALS_IMAGES_PHYSICAL_THUMB", true); //Create an hidden thumb file with parameters
@define("SHRENTALS_IMAGES_FALLBACK_NAME", ".notfound.png");
@define("SHRENTALS_IMAGES_FALLBACK_ROOT", JPATH_ADMIN_SHRENTALS .DS. "images");

require_once(JPATH_ADMIN_SHRENTALS .DS. "classes" .DS. "file.php");


class ShrentalsImages extends ShrentalsFile
{


protected $file;
protected $dir;
protected $mime;
protected $image_width;
protected $image_height;
protected $width;
protected $height;
protected $ext;
protected $types = array('', 'gif', 'jpeg', 'png', 'bmp');
protected $top = 0;
protected $left = 0;
protected $type;
protected $name;
protected $info;

Ok i edited the line to read..

@define("SHRENTALS_IMAGES_ALOWED_SIZES", '400x400');

but my images are still importing at the original size. Did I miss something?

Yes, of course, your images are uploaded in original sizes.

Cook create thumbs (copies) and put them in same folder with a '.' before (hidden file on UNIX)
You can decide to allow or not the physical thumb file creation.

If not, the image is outputed resized to optimize the file transfert. But using this functionality (not physical), you will use more CPU to generate.

For security, in both cases, you restrict the possible sizes, in order to :
- Do not allow attacks, creating too much thumbs
- Do not allow resizing incredible huge sizes and consuming CPU (DDOS)


Now, in your case, if you do not want to keep the original file :
- Delete it
- Replace the file by its generated thumb

(For this, my advice is to add a parameter, so you will be able to use it natively, or replacing file from anywhere in your component)

Hope it helps.
