Theme development

Hello, i'm new to Drupal (and this forum) and I haven't been able to find a solution for the following problem. I want to do a simple image gallery, where I have the images from a certain content type. Each image should be clickable and lead to node in question. No problem here, this was easy to create with Views-module using Display type "Grid". Now I have neat rows with four items on each of them.

Super weird; I created a custom field (called Opening Paragraph) for one of my content types (Page) ages ago, and it was working fine. I clicked onto my site today, and all of the sudden, that field and all of the existing content in it has disappeared.

I went into Content Types > Manage Fields, and I can see the field listed, and it seems to be stuck on "hidden" now (visible is no longer an option)?

Does anyone know why this might be?

I have 10 content types. And I want to group search result by content type (I use Apache SOLR 3.x and custom_search module). For example:

Content types:
-Type1
-Type2
-Type3
-Type4
-Type5
-Type6
.....

Search result:

Type1
---
---

Type2
---
---

Others

I'm trying to put two menu in the page which should behave more like

As of now we only have one header by default. How can i configure the menu so that there should be a two menus on top.

Is there any specific tutorials available ?

hello all
i am relatively new to Drupal
im having this little inquiry
i am currently using the "corporate clean" theme. what i want is the slideshow that shows up on the home page to show up in every page
please let me know how to accomplish the above
Many thanks

I have a content type called Realisation.
Realisation
Title
Body
Thumb Image

I create a Block View and a Page View
Page View
I display only Title, and the Body. I setup the path url parameter as "/MyRealisation"

In the block view
I only show a list of Thumb Image. I link my Thumb Image with the content.

When I click on my image, it's not using my custom Page View. I Notice that the path is wrong. It show node/62 instead of /MyRealisation/node/62
Is there any reason ?.
