Resizing images outside PW folders

[Roope]

I'm building a product site where single product page wouldn't have any image field on it but instead we would use product images from another folder outside PW folders. All images are named using product SKU number that we store to text field during product import.

Reason for this is that we already have images in place and we dont need (nor want) for images to be visible or uploadable through PW admin. Customer is used to mass update images via FTP and we don't want to break that.

So question is, can we still use API to resize images or is it impossible outside wire array and filesystem?

are you looking for something like this;

• foreach($page->images as $image) {
• $large = $image->width(500);
• $thumb = $image->size(100, 100);
• echo "<a href='$large->url'><img src='$thumb->url'></a>";
• }

details here

Thanks for your reply sakkoulas!

No, this isn't quite what im looking for since I wouldn't have any image field attached to product template.

Situation is more like this:

// set root for product images
$root = $config->urls->root . 'images/';

// set product image filename using product sku number
$name = $sanitizer->pageName($page->sku) . '_01.jpg';

// get product main image
$image = file_exists($root.$name) ? $root.$name : null;

// now, resize image using PW API
if ($image) $image = $image->size(300,200);

You could try using the ImageSizer class of PW.

$im = new ImageSizer($config->paths->root . "myimages/IMG_09.jpg");
$im->resize(100,0);

Yep, this looks right - thanks Soma!

And ImageSizer seems to create new image to the same path as original so I think this should work just fine.

I'll test it and report findings here!

OK, so this behaves as excepted. Defined image gets resized.

But it overwrites the original file so this is not perfect solution for my need. Is there a way to make it create size variation from original without overwriting? I didn't find any options for this in ImageSizer class so how is it done in API? Should I just first copy and rename original image and resize that one?

[Soma]

Yeah the naming is done by the PageImage I think.

Should I just first copy and rename original image and resize that one?

Yes, this is basically what Pageimage does internally. You can use PHP's copy() command.

Thanks! I got sizing working really fine here.

Just tried doing this but it doesn't seem to work anymore?
